Recently a problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server and Express. A patch is available to correct this problem (see section II below). BEA treats such possibilities with the highest degree of urgency and does everything possible to ensure the security of all customer assets. As a result, we strongly suggest the following action:

I. Read the following advisory.

II. Apply the suggested action.

III. If you know of any additional users interested in future security advisories, please forward them the registration instructions below.

I. ADVISORY

This vulnerability concerns a number of clear-text passwords that have been identified in BEA WebLogic Server and WebLogic Express. The following passwords were identified:

JDBCConnectionPoolRuntimeMBean password was displayed in clear-text via weblogic.Admin. The password field was properly restricted. The major concern here was a passerby seeing the password on the screen of a privileged user.

The default CredentialMapper stored the passwords in clear-text on disk. A knowledgeable attacker who had access to the disk files and knew how to extract passwords out of the binary data file could exploit this.

Several secrets internal to WebLogic Server and WebLogic Express concerning the encryption of passwords were potentially accessible to non-privileged users. An attacker who obtained these passwords, had extensive knowledge about the internals of WebLogic's encryption algorithms and had access to files that contained the encrypted passwords could have stolen the passwords. This includes passwords stored in config.xml, filerealm.properties and weblogic-rar.xml.

The following versions of WebLogic Server and Express are affected by this vulnerability

WebLogic Server and Express 7.0 and 7.0.0.1, on all platforms

II. SUGGESTED ACTION

Oracle strongly recommends the following course of actions:

Apply the appropriate Service Pack:

For WebLogic Server and Express 7.0 and 7.0.0.1

Upgrade to Service Pack 2 and download and apply the patch #7824669 from OracleMetaLink as per the instructions below:
• Select the Patches and Updates tab after logging in to OracleMetaLink.
• Click Simple Search.

• Enter the patch number. The patch number may be different for different product releases and platforms.
• Select the platform (or choose generic as applicable)
• Click Go.
• Click Download to download the patch.

When Service Pack 3 becomes available, you may use that Service Pack instead of Service Pack 2 and this patch.
